01 - Combine water, cinnamon stick, cardamom pods, cloves, ginger, and star anise in a medium saucepan. Bring to a gentle boil over medium heat.
02 - Reduce heat to low and simmer for 5 minutes to allow spices to fully infuse the water.
03 - Add loose black tea or tea bags to the saucepan. Simmer for an additional 3 minutes, extending to 5 minutes for stronger flavor.
04 - Remove from heat. Strain the tea through a fine mesh strainer into a teapot or directly into cups, discarding spices and tea leaves.
05 - Stir in sugar or honey to taste. Serve hot, garnished with a lemon slice if desired.
